Last place I have visited in Malaysia was Penang and I flew there from Langkawi, with AirAsia, again for 5€. My host didn´t have a car, but I could explore more just because there us public transportation on the island, not Langkawi alike, where you have to own a car or rent a bike. There are also many more places to go and today I will tell you all about them. I just regret I didn´t stay there few days longer… sigh, sigh, sigh.
If you want to be close to nature, go to India. It´s a place, where nature is everywhere, even in the city, even on the desert. You will see it sometimes with its flora but mostly by its fauna. Yes, I mean by the animals.
